In this video:

On December 21, 1898, Marie and Pierre Curie discovered the radioactive element radium (in the form of radium chloride), extracting it from uraninite. They first removed the uranium from the uraninite sample and then found that the remaining matter was still radioactive, so investigated further. Along with the barium in the remaining substance, they also detected spectral lines that were crimson carmine, which no one had yet documented or, apparently, observed. These spectral lines were being given off by radium chloride, which they managed to separate from the barium. Five days later, they presented their findings to the French Academy of Sciences.
